Verify that the Ethernet 10BaseT cable is securely installed at

 

both ends, and at least one PC is connected and powered on.

 

 

 

Verify that the correct straight-through or crossover cable is

 

installed. Refer to Installing the Hotwire 5620 RTU, page 8.

 

 

PWR LED is off.

Check that the power cord is securely installed on both ends.

 

 

 

If no LEDs are on, the power supply may be defective. Test the

 

outlet to verify power. If the problem persists, contact the NSP.

 

 

 

If other LEDs are on, the PWR LED may be burned out. Unplug

 

the unit and reapply power; watch all LEDs during the

 

power-on self-test to verify if the PWR LED is functioning.

 

 

TST LED is on.

A test initiated by the NSP may be active. Wait five minutes.

 

If the TST LED does not go off, contact the NSP.

 

 

Increasing the Number of End-User Systems

A single PC is attached to the Hotwire 5620 RTU using an Ethernet crossover cable. To increase the number of PCs, connect all PCs to an Ethernet hub using a straight-through cable. The Hotwire 5620 RTU can support up to 32 PCs. Verify any planned changes with the NSP.
